Question

I have an ajax request sending some data to a php file:

Ext.Ajax.request({ 
    url: 'update.php', 
    method: 'POST',
    success: function (){ alert("saved"); },
    failure: function (){ alert("not saved"); },
    params: { data: someData }
})

and update.php that has only two lines:

<?php
    $res = array('success' => false);
    echo json_encode($res);
?> 

The success function is always executed.
What can be the problem?

Answer 1

For me, the function failure should be called when there is a problem with the request. e.g. If the server is down or the page update.php do not exist anymore.
